Firefox says my operating system doesn't support upgrade. I have MAC OS X 10.5.6
When I tried to download the latest Firefox version, a message said that my operating system doesn't support the upgrade. But the information on download page says MAC OS X 10.5 or better is okay. My system is MAC OS X 10.5.6

Do you have a Intel processor or a PowerPC processor as your user agent suggests and Mach-O would indicate an even older OS X version than 10.5 (possibly OS X 9).
- Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.8.1.3) Gecko/20070309 Firefox/2.0.0.3
Are running Firefox in some compatibility mode via Rosette?

- Firefox 4 versions and later do not run on a PowerPC Mac.
- Firefox 4 and later require at least OS X 10.5 and an Intel Mac.

Thanks for your response--now I understand. Yes, my Mac is an older PowerPC Mac. I've upgraded Firefox to 3.6.20 and it's working fine. Not gonna buy a new Mac in this economy, ya know? I appreciate your help. Aloha from Hawaii.
You're welcome
For an unofficial Firefox 4 compatible version (TenFourFox) that runs on PowerPC Macs with OS X 10.4.11 or OS X 10.5.8 you can look at:
